Kerwin,

You were listed as the staff contact on the Part 72 clarification letter regarding permit exemptions, so I am 

reaching out to you regarding a follow-up question I had after reviewing the letter. 

Based on my understanding of the letter, the "excess of 2,000 active individual units" accounts for the 

multiple units included in the total of 942 subject items for the 4 different categories referenced in the 

letter (Backup/Standby, Emergency, Exempt, Insignificant). Do you have information regarding the 

number of individual active units for each of the 4 categories. I am trying to get an idea of how many of 

the 2,000 active individual units did claim an exemption. I assume that those sources in the Exempt 
category in the database would reflect this information. I understand that this would not include all 

sources that utilized an exemption under Section 202, since all exemptions do not require notification 

under the provisions of Part 72 in addition to any sources that may not have been entered into the 

database.

Thanks in advance for your help. Feel free to give me a call if you have any questions.

Ashley
